Obviously that “top Rabbi” doesn’t have Ruach HaKodesh… So how is he to be believed regarding others?!? Isn’t that ludicrous?!
According to that logic, the gemara could not have stated that there is no longer ruach hakodesh, yet it does.
(I’m not arguing that there can’t be a lower level of ruach hakodesh than the gemara is referring to.)
